Research and Teaching Interest

Various kinds of novel fiber sensors are proposed and manufactured by a femtosecond laser and fusion splicing for real-time and online sensing of parameters such as temperature, concentration, humidity, pressure and strain. Compared with the existing commercial grating-based fiber sensors, the temperature resistance and sensitivity of the sensors are improved greatly and particularly suitable for harsh environment. The sensitivity is improved by 100～1000 times and the detectable temperature is increased from 350℃ to 1200℃ with low cross sensitivity. Some sensors have been marketed and applied for online temperature detecting in the high-voltage switch cabinet in Sichuan State Tax Bureau.
